Which statement describes a MetroCluster environment in clustered Data ONTAP?

While MetroCluster involves FC and Ethernet switches, it is not described as 'a single cluster at each site'; rather, it is one logical cluster spanning two sites.

This option incorrectly limits the interconnect to only FC switches and also mischaracterizes the cluster topology.

This option correctly identifies an HA pair across sites using FC switches, but option D's emphasis on 'extended cables' better captures the geographical separation aspect inherent to MetroCluster.

A MetroCluster configuration in clustered Data ONTAP creates a single logical cluster spanning two sites, where a high-availability (HA) pair has its controllers connected across the distance using extended cables and typically FC switches, providing synchronous replication and disaster recovery.
